The Path Computation Element Communication Protocol (PCEP) provides
mechanisms for Path Computation Elements (PCEs) to perform path
computations in response to Path Computation Clients (PCCs) requests.
Although PCEP explicitly makes no assumptions regarding the
information available to the PCE, it also makes no provisions for
synchronization or PCE control of timing and sequence of path
computations within and across PCEP sessions. This document
describes a set of extensions to PCEP to enable this functionality,
providing stateful control of Multiprotocol Label Switching (MPLS)
Traffic Engineering Label Switched Paths (TE LSP) via PCEP.
